To @ZZ whom it may concern.-

Be it known that we, SIVERT PETERSON and AUGUST BALAND, citizens ottheUnited States, residing at the city of Menominee, in the county ofDunn and State of NTisconsin, have invented certain new and usefulImprovements in Railway-Switches; and we do hereby declare the followingto be a full, clear and eX- A act description of the invention,such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to a new and improved railway-switch and meansfor operating the same both automatically and by hand.

The invention has for its object the production of a cheap and simplerailway-switch capable of being automatically operated from a passingtrain and also of being operated by hand, the switch-moving mechanismbeing.

firmly locked in either of its positions and prevented fromaccident-ally shifting therefrom.

The invention comprises the detail construction, combination, andarrangement of parts, substantially as hereinafter fully set forth, andparticularly pointed out in the claims.

In the accompanying drawings, Figure l is a view in side elevation,showing a portion of a car. Fig. 2 is a plan View. Fig. 3 is a v erticalsectional view on the line 00 x, Fig. 2. Fig.4 is a similar view on thelineg/y, Fig. 2. Fig. 5 is a detail view of the means for operating theswitch by hand. Fig. 6 is a transverse sectional view of the automaticoperating mechanism.

Referring to the drawings, Adesignates the main track, a the side track,and a the switch-rails of the former. To these switchrails at theirouter ends is connected a crossbar a2, with which engages the uprightarm b of a movable cross-head b. The ends of this the cross-head ismoved from one side to the other, and thus lock the same in place. Fromeach of these locking-arms extends aplate or wing h5, which serves as aweight for said arms. Through a slot or opening h6 in the lower edge ofthe cross-head projects an arm B, which at one end is secured rigidly toa head or block C, pivotally mounted at its center between upper andlower end bars of frame b2. In the ends ot' this head or block O areupper and lower slot-s CZ d, in the latter of which are pivotallysecured parallel operating-bars D for operating the switch on the mainline, while in the former slots are secured bars D', through the agencyof which the switch is operated from the side or branch track. At theirrear ends operating-bars D are pivotally secured in the slotted ends ofa cross-head cl2, pivoted by a bolt d3 to the top bar of a frame E,attached to boards b3 and projects a vertical arm f, having an uppergrooved or slotted end, into which extends a stud or pin f4 ofcross-head cl2. From this rock-shaft at its ends project oppositelateral arms j" f2, to the outer ends of which arepivotally connectedthe lower ends of vertical bars f3, the upper ends of which areprojected through slots or openings in adjacent ties t.

G G are two sets of depressible bars, each set being composed of twohars g, pivotally connected together at their rounded meeting ends andpivoted at their outer ends by nutted bolts g', projected through slotsin parallel guide-bars g2, securely fastened to the crossties bykeeper-plates g3. The upper ends of bars f3 extend up between theparallel guidebars g2 and against the under sides of the bars g, wherebyby depressing either set of these bars the bar f3 in contact withsuchdepressed set will be lowered and effect the rocking of shaft F,causing through the agency of the short vertical arm thereof the turningof crosshead d2 and the movement of the parallel bars D. The latter willcause the head or block C to turn on its pivot and through the agency ofarm B will move the cross-head h toward the right or left, according asto which set of depressible bars G or G has been operated, and saidcross-head will be locked in position ICO by one of the arms b4. It isobvious that by extending the operating-bars D double their length theycan be connected with switch mechanism the counterpart of thathereinbefore described for operating the switch by a train moving in anopposite direction; also, said switch can be operated by similarmechanism connected with the bars D.

To enable the switch to be set or operated by hand, we connect to theouter end of arm B a link-bar or pitman H, which is extended through anopening in one of the boards h3 and pivotally connected between parallelcheeks h ot a collar h', fast upon a vertical rod or shaft h2, whichlatter is mounted at its lower end in a projecting end of a tie. Thisrod or shaft is projected up through a stand or frame I at-one side ofthe track, and above thc top board 'L' of said stand said rod is squarein cross-section, and upon this square portion is a block t', held asagainst upward movement by a collar or washer i. This block is providedwith a circular hole or openingt'2 and a square elongation i3 thereof.In `a slot or groove in the outer lower end of this block is pivotallysecured the square end of an arm 4, by which when in a horizontalposition the block 'i' can be moved, so as to make the square elongationi3 surround the square portion of rod h2 and cause the latter to turnwith said block and arm,and thus effect the setting of the switch. Bydropping arm i4 into any one of the grooves or recesses 5 in the edge ofthe top board 'L' the block t" will be drawn forward and freed fromcontact with rod h2. The arm 'i4 when in a lowered vertical position canbe locked as against operation by a padlock i, passed through an eye orstaple il, attached to the inner end of said arm, and which is projectedbeyond the slotted end ot' the block when the arm is lowered. A signal Jis inserted on rod h2 to indicate the position ot' the switch.

The switch may be operated by any known means or any means hereafterdevised adapted to depress either one or the other of the depressiblebars G or G'.

lVe claim as our inventionl. The herein -described railroad -switch,comprising the switchrails, the sliding crosshead connected thereto, thecorresponding locking-arms pivoted to said cross-head, the pivoted heador block having an arm engaging said cross-head, and the operating-barsconnected to said head or block, substantially as set forth.

2. The herein described railroad switch, I

comprising the switch-rails, the sliding crosshead connected thereto,the corresponding locking-arms, the pivoted head or block having an armengaging said cross-head, the operating-bars connected thereto, thepivoted cross-head to which said bars are also connected, the rock-shaftfor operating said latter cross-head, and the depressible bars foreffecting the rocking of said shaft, substantially as set forth.

3. The hereindescribed railroad-switch, comprising the switch-rails, thecross-head connected thereto, the pivoted head or block having an armengaging said cl'osshead, the operating-bars connected thereto, thepivoted cross-head to which said bars are also connected, the rock-shafthaving an upwardlyprojecting arm engaging a stud of said pivotedcross-head and also having opposite lateral arms at its ends, thevertical bars connected to said lateral arms, and the depressible barsfor effecting the lowering ot' said vertical bars, substantially as setforth.

4:. The combination, with the switch-rails, of the sliding cross-headconnected thereto, the arm having a pivoted bearing or support andengaging said sliding cross-head, the link-bar or pitman connected tosaid arm, the vertical rod or shaft to the lower end of which saidpitman is connected, the stand or frame through which said rod or shaftis extended, the block on said rod or shaft having a hole or opening andan elongated slot corresponding with said shaft, and also having anouter slotted or grooved end, the arm pivoted in said slotted or groovedend, and means for locking said arm, substantially as set forth.

In testimony whereof we aix our signatures in presence of two Witnesses.i
